FUME .AND HEAT REMOVING- DEVICE.

Application led November 3, 1924. Serial No. 747,475.

My invention relates to stoves of all descriptions especially of the types in use at the present time. Stoves as at present constructed sometimes have no means provided for removing the fumes of cooking foods or the poisonous fumes that are caused by imperfect combustion.

Most of the stoves of the gas-electric and coal and wood type are provided with either a warming closet or a shelf and an enclosure at the back. These cause the fumes that rise under the former to be forced towards the front of the stove and up into the room. Naturally these fumes will strike into the face of the person tending to the cooking.

Many devices have been invented to remedy this condition but they have been either too large, and thus a hindrance or they eannot be applied to the modern type of stove.

Another fault with many of these devices is that they function only at certain times` such as when the hoods are pulled over the stoves.

The object of my invention7 therefore,is to provide means that will remove these fumes by providing at the under side of the warming closet or shelf an inclined plane that will direct said fumes to a chamber at the back of the stove.

Another object of my invention is to provide means that can readily be made a standard part of any stove.

I attain my object by providing a chamber that is attached to the rear of the stove and has an outlet at the top. Together with this I provide at the under side of the warming closet or shelf7 a rearwardly inclined surface that will cause the fumes to enter the chamber and then be carried away.

To accommodate the complete area of the stove I provide a sliding member that can be pulled forward in the same plane as the ineline abovementioned.

Thus my device is operable at all times either in part or in whole, as the heated fumes will always follow the inclined plane.

I also provide means for preventing side drafts from carrying the fumes to the side of the stove and into the room.

I carry my invention into practice in the manner illustrated by the accompanying drawings constituting a part of this specification:

In said drawings:

Fig. l is a perspective View of a standard range showing my invention as a part of the same and the connection of the chamber to the flue;

Fig. 2 is a section taken along the center line of the flue, thus showing the auxiliary sliding member pulled out to its full length; this view also shows how the chamber increases the area of the stove surface, and also shows means within the flue for aiding the fumes to escape due to the suction created by the fire in the stove;

Fig. 3 is a perspective view of my chamber;

Fig. 4 is a perspective view of the construction of the auxiliary sliding member and the means for attaching the same to the under side of the inclined attachment to the warming closet;

Fig. 4a is a section taken on the line la-4" of Fig. 3, showing details of construction;

Fig. 5 is a similar section to Fig. 2 showing a range with the flue in a more rearward position, also anti-draft devices;

Fig. 6 is perspective view of my chamber with the outlet at the side of the flue, and also shows side plates that extend under the warming closet to eliminate side draft;

Fig. 7 is a perspective view of the auxiliary sliding member having side wings as shown;

Fig. 8 is a perspective View showing my invention in relation to a gas or el-ectric stove with side oven;

Fig. 9 is a perspective view showing my invention in relation to a gas or electric stove with bottom oven and no shelf;

Fig. l0 is a perspective view of my device on an enlarged scale in relation to a restaurant range showing the auxiliary slides made in a number of units; and

Fig. ll is a vertical section of Fig. 10.

To the chamber a is attached the member Z) having an inclined surface b', sides 62 and a front part b3 provided with` an over turned lip b4. The back plate of the stove is removed and thus is not shown. The chamber is attached to the stove brackets o by means of bolts c2 through holes a provided in the side anges a2 of the chamber a. The upper part of the chamber a is tapered to an outlet Z to which is attached the pipe e. A hole be is provided for the flue c2 to pass through surface b.

The member Z) is attached to the under side of the warming closet f by bolts f through holes b5 in the lip bt. rIhe bottom. side a. of the chamber becomes a continuation of the surface of the stove c.

Thus. instead of a pocket being formed under the warming closet, an avenue of escape is provided for the fumes in the rearward direction To accommodate the complete area of the stove heating surface I provide a member .f/ which slides forward in the same inclined plane with the surface Owing to thc fact that the warming closets are relativel)Y narrow, I tind it preferable to constructy the member y'/ of units g and 02. rIhe unit g slides in brackets L which are held to member by rivets li. The lips (/f* of units g strike against the stops /z2 of brackets 7L and limit the forward movement of the unit g.

Countersunk bolts i set in the unit g', work in slots j in the unit (/2. and the extensions 7e of the unit of and limit the forward movement of the unit g2.

In Fig. 3 it will be noted that a kettle Z can be set on the bottom surface o of the chamber' and thus added space is lett for other kettles,

In Fig. 5 the bottom f3 of the warming closet f2 is at an incline and a false bottom my is inserted into the closet.

The chamber' at is provided with exten- `sions n- The sliding member 0 having downwardly extending portions 0' is mounted to the underside of the closet .7'2 by rivets 72 sliding in slots 02 in member 0.

In Fig. 8 the chamber a provided with an out-let a is shown attached to the stove Q and the slide r is suitablyv mounted to the under side of the shelf S, which is inclined.

In Fig. 9 the chamber zt having sides t', top f2 outlet f3, and back t4, is attached to the top of the stove u b v rivets u- The lslide c is mounted to the inclined under side of the top In Figs. l0 and il the chamber u: is attached to the stove a; bv brackets ,1/ and is provided with outlet te and shelf 2v2 having an inclined under surface nf to which are suitably mounted sliding units Doors 2 are provided inthe upper side of the front wall zc" of the chamber il' t'or readilyv cleaning out the chamber.

In Fig. l I show means for aiding in withdrawing the fumes from chamber a, in the form ol' a Venturi tube et. lThe portion e of the pipe c connects to the tine at an angle. A damper e2 is added to shut ottl the chamber from the tlue.
